Conventional Soft Contact Lenses are recommended for use about a year. When soft Contact Lenses are used daily, they undergo lot of wear and tear. This degrades the surface qualities and eventually reduces the lens performance to unacceptable levels. When the patient starts having problems like discomfort, redness, reduced vision and wearing time, it is bet to replace the lenses irrespective of the time. Even if the lens is in good condition, it is not medically fit for use, as it can cause harm to the eyes.
